4. Best Practices to
Store Milk
4.1 Immediate Cooling
Milk should be chilled down below 4°C (39°F) within two hours of being drawn. Immerse the can in cold water or use a bulk milk chiller. The farm is where efficient milk transportation and storage starts. To stop germs from growing, milk's temperature needs to be quickly lowered as soon as it exits the cow. Within a few hours of milking, milk must normally be chilled down below 40–45°F (4–7°C) according industry standards. This quick-freezing process is essential to maintaining the integrity of the milk and adhering to food safety laws; it is not just a suggestion.
4.1.1 Essential Cooling Methods for Dairy Farms
Several technologies are
employed on dairy farms to achieve optimal milk cooling:
(i)Plate Heat Exchangers
(PHEs)
These
are some of the most economical and effective ways to chill milk in advance.
Before the milk enters the bulk tank, PHEs employ a sequence of thin stainless
steel plates to transfer heat from the warm milk to a cooler medium, usually
chilled water or well water. This considerably lessens the strain on the bulk
tank's refrigeration equipment.
The
main on-farm storage option is these insulated, refrigerated tanks. Their
purpose is to keep the milk at a steady, low temperature until it is collected.
Modern bulk tanks frequently include sophisticated cooling systems and motors
that use less energy.
(iii)Chilled Water Tank
Systems & Immersion Coolers
Cooling
probes can be submerged in milk or systems that circulate cooled water around
milk cans can be used for smaller operations or as additional cooling. To keep
the milk at the proper temperature, it is essential to properly insulate the
pipes and the milk storage tanks to reduce heat transfer from the surroundings.
For reliable operation, cooling equipment must also get routine maintenance and
calibration.

At every step of the milk storage and transportation process, strict hygiene and sanitation procedures are essential, even beyond temperature control. Equipment, people, and the environment are only a few of the causes of contamination. Preventing bacterial development and guaranteeing the safety of the milk depend heavily on maintaining a clean and sterile environment.
On-Farm Hygiene Practices
(i)Clean Milking
Equipment
After
every usage, all milking apparatus, including as collecting buckets, pipelines,
and milking machines, needs to be meticulously cleaned and sanitized. By doing
this, the accumulation of milk leftovers that may contain germs is avoided.
(ii) Bulk Tank Cleaning
Farm
bulk tanks need to be cleaned thoroughly and on a regular basis. Rinsing,
washing with permitted detergents, sanitizing, and then rinsing again are
usually the steps involved in this process. Automated cleaning systems are
widely used and very efficient.
(iii) Milking Environment
It
is important to maintain a clean and contaminant-free milking parlor and milk
house. Additionally crucial are adequate ventilation and insect control.
(iv) Personnel Hygiene
Workers
on dairy farms who handle and milk milk are required to follow stringent
personal hygiene guidelines, which include wearing clean clothes and cleaning
their hands properly.
4.2 Use Approved Containers
Milk should always be kept in certified plastic cans or food-grade stainless steel containers. Never use unsealed containers or rusted buckets.
ü Keep
milk in food-grade, BPA-free plastic, glass, or stainless steel containers.
ü Before
every usage, containers need to be cleaned and sanitized.
ü Steer clear of utilizing reusable, difficult-to-clean plastic bottles or open buckets.

4.3 Regular Cleaning
Clean storage tanks daily. Residue in tanks encourages bacterial growth, off-flavors, and spoilage.
4.4 Keep It Covered & Sealed
To avoid dust, insects, or smells contaminating containers, always cover them firmly.
Raw milk should never be kept in the refrigerator uncovered.
4.5 Avoid Temperature Fluctuations
- Keep milk in the coldest part of the fridge — not the door.
- Don’t leave milk out for long periods during serving or transport.
4.6 Use FIFO (First
In, First Out)
- Label stored milk with the milking
date.
- Use older milk first to avoid
spoilage and waste.
4.7 Transport Properly
- If transporting raw or pasteurized
milk, use insulated coolers with ice packs.
- Deliver to processors or consumers as
quickly as possible.
4.8. Keep It Clean
